Answer:

26π

Step-by-step explanation:

Hmm... This one is a little hard to understand because of the LaTeX.

Any way, way back to the question. A useful piece of information:

<u>The formula for finding the circumference of a circle is 2πr or π · d :</u>

We first need to find out what x is.

Since 2 times the radius is the diameter, we can set up our equation like this:

2(x + 6) = 3x + 5

Solving gives:

2x + 12 = 3x + 5.

We subtract 2x from both sides:

+12 = x + 5

Subtract 5:

So x = 7.

Now we can plug-and-chug:

7 + 6 = 13 times 2pi (this is the radius)

21 + 5 = 26 times pi.

<u>Check:</u>

When we check 13 (radius) times 2 should equal the diameter(26)

13 * 2 = 26.

So we are correct. The answer 26π is correct.

Solve for y. 4y+5/3 = y-8/2 y = -4 y = -5 y = -8

horrorfan [7]

Answer:

Step-by-step explanation:

$\dfrac{4y+5}{3}=\dfrac{y-8}{2}\qquad\text{multiply both sides by }\ 2\cdot3=6\\\\6\!\!\!\!\diagup^2\cdot\dfrac{4y+5}{\not3_1}=6\!\!\!\!\diagup^3\cdot\dfrac{y-8}{\not2_1}\\\\2(4y+5)=3(y-8)\qquad\text{use distributive property}\\\\(2)(4y)+(2)(5)=(3)(y)+(3)(-8)\\\\8y+10=3y-24\qquad\text{subtract 10 from both sides}\\\\8y=3y-34\qquad\text{subtract 3y from both sides}\\\\5y=-34\qquad\text{divide both sides by 5}\\\\\boxed{y=-\dfrac{34}{5}}$
